[julia-users] How to run a DOS command?

[KK Sasa]

Is there command like R's command 「system」

     system("XXX.bat")

or Matlab's 「dos」in Julia?

     dos('XXX.bat','-echo');


I have checked 
http://julia.readthedocs.org/en/latest/manual/running-external-programs/, 
but still don't understand how to call DOS.

Thanks.
